昆虫传播的植物病毒往往给作物造成巨大的经济损失,因此选育具有抗病毒的作物品种是目前防治病毒危害的重要手段之一。当前,随着现代化进程的加快,近地面臭氧(O3)浓度不断升高。但这种变化对作物抗性品种的影响如何,目前仍不清楚。中国科学院动物研究所戈峰研究员领导的种群生态与全球变化研究组模拟研究了近地面臭氧(O3)由目前40ppb浓度增加到未来80ppb情景下植物对蚜传病毒的作用。以抗马铃薯Y病毒(PVY)的烟草品种和常规对马铃薯Y病毒(PVY)敏感的烟草品种为
Insect-borne plant viruses often cause huge economic losses to crops. Therefore, breeding of antiviral crop varieties is one of the important measures to prevent and control the virus. At present, as the process of modernization accelerates, the ozone concentration near the ground (O3) continuously increases. However, it is still not clear what effect this change has on crop resistant varieties. The Group on Geomorphology and Global Change, led by Professor Ge Feng, Institute of Zoology, Chinese Academy of Sciences, simulated the effect of near-surface ozone (O3) from the current 40 ppb concentration to the next 80 ppb plant-borne virus. Tobacco varieties resistant to potato virus Y (PVY) and conventional tobacco varieties susceptible to potato virus Y (PVY) were
